Abstract

BACKGROUND AND PURPOSE: Behavioural-variant frontotemporal dementia (bvFTD) and Alzheimer's disease (AD) patients experience behavioural and emotion recognition alterations, yet understanding of how socioemotional processing is affected with disease progression is minimal. Additionally, evidence suggests that bvFTD patients with limited brain atrophy on neuroimaging at presentation (bvFTD-la) have a more benign course than those with marked atrophy (bvFTD-ma). Longitudinal investigation of these patients, however, is lacking. METHODS: We investigated general cognition, emotion recognition and sarcasm detection in 20 bvFTD (8 with limited brain atrophy) and 17 AD patients longitudinally and used mixed models analyses to determine the level and rates of decline across groups over time. RESULTS: At baseline, all patient groups performed worse than controls on general cognition and emotion recognition measures. The bvFTD-ma group showed significant impairment on the sarcasm detection task compared with controls. Longitudinally, an overall effect of time was present for general cognition (p<0.001); however, the rate of decline did not differ across groups. Trends for interactions between time and diagnosis were observed for both emotion recognition tasks (p=0.055; p=0.062), with the bvFTD-ma group declining more rapidly than AD or bvFTD-la groups. On the sarcasm detection task, the bvFTD-ma and AD patients declined, whereas bvFTD-la patients remained stable over time (p=0.002). CONCLUSIONS: Tasks of sarcasm detection represent a clinically useful tool to differentiate between bvFTD and AD at baseline. Furthermore, tasks of socioemotional functioning can track progression within bvFTD and identify bvFTD patients more likely to show a faster rate of decline.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
